The key to learning is to stop passively consuming information and start actively engaging with the ideas we encounter. Think about the student who writes down what her professor says verbatim, versus the student who summarizes the information in her own words and then connects it back to concepts she’s learned before: Who do you think learns more?
Humans are bad at retaining information. We forget most of what we read and hear. However, when you write down the things you’ve learned, you retain them far better. Even if you never re-read what you’ve written, the simple act of writing something down increases brain development and memory.
